#1 way to go..definate improvement ..I think the owl one is really cute..
I'm pretty new to making bows so I don't have much to go on..I'd just work on your spikes a little to try and make them more uniform or the same length.
I myself have a terrible time w/them and found this to be helpful http://hairbowswonderworld.blogspot....-boutique.html
as for your twisted bow I think your doing good..do you use a template or free hand? I have the nbng but also bought just daisy's tutorial..and It's really good helping with technique and she sells it for a fair price compared to some of the other instructions and tutorials I've seen.
Best of Luck
